In this video, we drill into the other most important normal form, learning what Fifth Normal Form (5NF) is, why Boyce-Codd Normal Form is not enough, and examples of why 5NF can be such a challenge to implement.
Until I read CJ Date’s Database Design and Relational Theory (2nd edition), my level of appreciation for 5th Normal Form was somewhat limited, but that’s mostly because I didn’t understand it well at all. I liked the connection trap example in this article, but Date’s book was the first really good explanation of 5NF and just how powerful it is. My hope is that I was successfully able to convey that power to audiences.
